Title: Device for testing watermeter
Inventor: IKEDA YOSHIO
IPC: G01R35/04
Filed: 1980-10-02
Abstract: PURPOSE:To perform more accurate measurements than analog devices, by a tester wherein power of an electric power system is measured in a digital manner and average power measured at the same time by a wattmeter to be tested is calculated by the same device used for the digital measurement, thereby to display a difference between both the results. CONSTITUTION:A microcomputer 8 judges the presence or absence of a level change of a pulse signal from a test pulse detector 6 every when a pulse signal from a reference time generator 5 is input to a parallel data detector 7. When the level change is detected, a sample value is latched from a point between A-D converters 3, 4 and the detector 7. Then the product of voltage and current is calculated, thus obtained products are added and the times of such addings are counted. The measurement is completed after given times of operations are performed. Average power obtained by this measurement within a certain measuring time is calculated on the basis of data stored in the microcomputer 8. The microcomputer 8 displays in a digital manner a difference between thus calculated average power and average power measured by a wattmeter 10 to be tested. By so doing, a reference wattmeter is not required and the more accurate measurement can be performed comparing with the prior device in which power is computed by multiplying in an analog manner.

Title: Mobile communication system, mobile communication base station and mobile station for mobile communication
Inventor: TANIGUCHI TERUTAKA
IPC: H04W4/04
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To provide a base station where transmission quality of a signal can efficiently be made stable. SOLUTION: A base station 3 of this mobile communication system transmits a base station communication signal with a relatively higher output so long as a train is present in a fading block in a transmission block. Hence, even when part of data sent from a base station is missing owing to fading, a mobile station 2 restores the transmission data from the base station in an excellent way. Thus, even under an environment of fading, the mobile station 2 can display an image and characters with prescribed quality or over on a display section. Furthermore, since the base station communication signal is sent with a high output only to the fading block, the power consumption can be reduced in comparison with the case that the power is set higher over all the transmission block. Thus, the transmission quality of the base station communication signal can efficiently be made stable.

Title: Detector for wide angle light emitting source
Inventor: INOUE KIMITAKA
IPC: G01J1/02
Filed: 1985-06-25
Abstract: PURPOSE:To make it possible to reduce a measuring error even if the light emitted from a wide angle light emitting source is detected by a minute caliber detector, by using a lens for converging the light emitted from the wide angle light emitting source to convert the same to parallel light and a lens for condensing said parallel light. CONSTITUTION:The optical arrangement of the lens 2 to a wide angle light emitting source 1 and that of the detector 5 to a lens 4 are made symmetric around a filter 3. Therefore, light having the same caliber as the light emitting source 1 can be detected by a light receiving surface 6. The filter 3 permits the incidence of light when the optical output of the light emitting source 1 is high output of +10dBm or more. Because the light passing through the filter 3 is parallel one, if the filter 3 is vertically inserted in parallel light, the incident angle of parallel light to the filter 3 becomes constant. Therefore, the effect in the incident angle characteristics caused by the filter 3 can be prevented.

Title: Method and apparatus for bonding of curing film
Inventor: SHIMADA YUKINOBU
IPC: B29C65/48
Filed: 1985-06-25
Abstract: PURPOSE:To closely bond a curing film exactly and quickly without leaving air bubbles by a method in which the film is bonded by continuously applying a tensional force to expand it bilaterally from the widthwise central portion from the previous period of bonding to the ending of bonding by rotation of an impeller and a press force toward the face to be cured to the impeller. CONSTITUTION:To give a tensional force to the longitudinal direction of a curing film 1, a braking force against the rotation of a roller 2 is applied. Lateral tensional force to be applied during the period from the previous time of bonding to the ending of bonding is applied by moving an impeller 4 formed of an elastic soft material, e.g., resin foam, rubber, or brush, along the face 3 to be cured while turning it on the curing film 1 already bonded and by pressingly contacting the film 1 with the periphery of the impeller 4 over the half- circular or more distance. While giving both the tensional forces, the film 1 is bonded to the face to be cured by pressing it with the impeller 4, and therefore, close bonding of the film 1 of wide width can be attained exactly without wrinkles and air bubbles.

Title: Method for behavioral analysis of piston
Inventor: AKEMOTO KISHIYU
IPC: G01M15/06
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of detect errors because of various external causes as much as possible in a sensor which detects a gap between a piston and a cylinder liner during operation of an engine. SOLUTION: A sensor output signal of a sensor 8a which detects a gap between a piston and a cylinder liner is inputted to a first and a second gate process circuits 21 and 22. A minimum value at the operation when a piston skirt can be regarded as being in a slide contact with the cylinder liner is taken at the second gate process circuit 22 and outputted to a zero point correction process circuit 26. The zero point correction process circuit 26 obtains a deviation of the minimum value at the operation from a reference value and corrects a zero point by adding the deviation to the sensor output. Even when the sensor is displaced by a thermal expansion difference due to a difference in material of the cylinder liner and the gap sensor, the zero point is corrected and therefore, occurrence of an error to the detect value during the operation of an engine can be prevented.
